Abstract (en)
[origin: CA3168548A1] A mold, more particularly a casting mold for producing microstructures, more particularly microneedle arrays, has a main part (10). A plurality of recesses (14) are provided on a top face (12) of the main part (10) and are intended to receive material for producing the microstructure. In order to improve the quality of the microstructure to be produced, in particular during a drying process, channels (18) are provided on the top face (12) of the main part (10) and each channel is connected to at least one of the recesses (14).
